2014 LTZ Z71 Adding Navigation

[Cheverado]

So yes I've done a search and can't find the answer I'm looking for. A local guy is selling the radio and 2 modules (plz see pic) from a High country vehicle.  My question is - with both modules and the radio, do I still need to bring my truck to the dealership to make this work?

You need only the HMI module but the dealer can't help you. They can only program it with your vin which does not have NAV. Search this site. There are third party vendors that you can send it to and get it properly programmed.

@Cheverado, I'd recommend WAMS (http://www.whiteautoandmedia.com/) or MVI (https://www.gm-navigation.com/).  Chris (WAMS) does a lot of custom programming for a lot of the vendors including MVI.  Anthony (MVI) has top notch customer service.  If you're interested, they may be able to upgrade your system some more like adding Apple CarPlay and Android Auto but that would require a newer HMI at least.

I have found my GM Nav completely useless. Last weekend we were looking for a store on it. My wife found on her phone was 3 blocks away and the pickups' was 9 miles away. We then manually typed the address in and it put me on the wrong side of the street. Now being on the wrong side doesn't sound like the end of the world, but it is when all 5 lanes are packed with cars. I hate spending money on options that I never use or that are junk like this, but it was already ordered on this pickup. I will stick with either garmin or a cell phone we already have.
